COMBINED BEVEL AND WHTER.

SPECIFICATION forming part of Letters Patent No. 707,461 dated August 19, 1902. Application filed November 30,1901. $erial in. 84,231. a. model.)

To all whom, it may concern.-

Be it known that 1, CHARLES R. STEDMAN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in a Combined Bevel and Miter, of which the following is a specification.

My invention relates to improvements in combined bevels and miters, and has for its general object to provide in such an instrument a construction whereby when one of the blades has been set at the required angle to the stock for a certain miter the parts employed in determining the angle of the said blade may be adjusted out of the way, this to leave the bevel formed by the blade and stock free to be used with the same facility as the ordinarybeveli. 8., a bevel not equipped with miter attachments. From this it follows that when it is desired to use my improved instrument simply as a bevel the miter attachments will not interfere in any way with such use.

Another object of the invention is to pro vide a combined bevel and miter which possesses a radius of action of over three hundred and ten degrees and is adapted to be applied with equal facility to exterior and interior angles.

\Vith the foregoing in mind the invention will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which- Figure l is a perspective view illustrating the several parts of my combined bevel and miter in their proper operative positions; Fig. 2, a top plan View; Fig. 3, an enlarged transverse section taken in the plane indicated by line 3 3 of Fig. 1; Fig. 4, a similar view taken on line 4: 4 of Fig. 2, and Fig. 5 a detail longitudinal section taken in the plane indicated by line 5' 5 of Fig. 2.

In the said drawings similar letters of reference designate corresponding parts in all of the several views, referring to which- A is the stock, 13 the bevel-blade, C the auxiliary or miter blade, and D E the leaves, of my improved instrument. The-stock in the preferred embodiment of the invention comprises side sections c b, an interposed longitudinal partition or division-plate c, a

rivet or screw d, connecting said sections and plate adjacent to one end, and a clamping means, such as a bolt e, having a spacingcollar f shrunk thereon at an intermediate point of its length, and nuts 9 g on its ends, connecting the sections and plate adjacent to the opposite end. Said stock is provided between the plate 0 and side section a with a pocket It to receive the blade B and between the plate a and side section b with a pocket 'i to receive the leaves D E, and it is also provided in the side section b with a pocket j for the blade C andin the plate a with a notch 7.: to receive the extended portion of the pintle L, presently described. The bevelblade Band theauxiliary or miter blade 0 are both pivoted on the bolt 6 of the preferred clamping means, and the former is provided with a longitudinal slot Z. The leaves D E are pivoted to the blade 0 and plate 0, respectively, preferably by means of countersunk rivets 0 0 as shown, and their lapped ends are connected by the before-mentioned pintle L, which has an extended portion m, Figs. 2 and 3, designed to be readily placed inand as readily removed from the slot 1 of blade B. At the points marked a the leaves D E are provided with semicircular notches of a size to receive the spacing collar or washer f. By virtue of the said notches in the leaves D E and the fact that the distances 0 L c L are greater than the distances be tween the points 0 o and the bolt 6 it will be i seen that my improved instrument possesses a radius of action of over three hundred and ten degrees and is applicable to exterior angles as well asto interior angles. When the instrument is applied to an exterior right angle, for instance, the notches n will seat the spacing-collar fand enable the blade 0 and the stock A to assume the necessary positions at right angles to each other, with the blade 13 extending from the apex of the angle.

In practice when it is desired to use my improved instrument simply as a bevel the pintle L is withdrawn from the slot 1 in blade B, the resiliency of the leaves D E in the preferred embodiment of the invention permitting of this being readily done. The leaves D E, together with the blade C, are then swung into their respective pockets in the stock A, after which the nut g of the clamping means is tightened to secure them in such position, and the nut g is tightened to secure the blade B at the proper angle to the stock. With this done the blade 0 and leaves D E are entirely out of the way, and hence the instrument may be used as a bevel with the same facility as an ordinary bevel. When it is desired to use the instrument as a miter, the stock A and blade 0 are placed in the required angle, Fig. 1, and the nut g of the clamping means is tightened, the blade B being meanwhile in any position Where it is out of the way. The blade B. is then properly positioned, the pintle L is pushed into the slot Z thereof, and the nut g is tightened,when the angle described by stock A and blade B will represent one-half of the angle described by the said stock and the blade O.v If it be now desired to retain the full angle, both blades B C may be left in the position stated; but if only half of the angle is preferable the pintle L may be drawn out of the slot 1 and the leaves D E and blade 0 placed in their respective pockets in the stock and secured in such position by the tightening of the nut g. The extended portion of the pintle L constitutes a lateral projection on the leaves for entering the slot Z of the blade B and determining the position of the latter, and while I prefer to employ the pintle for the purpose and depend on the resiliency of the leaves D E to permit of it being readily inserted in and withdrawn from the slot ZI do not desire to be understood as confining myself to such construction, as the projection may be of any character and placed in and withdrawn from the slot in any approved manner.

I prefer to permanently connect the leaf D to blade C, but do not desire to be confined to such connection, as when desired a detachable connection might be employed, this to permit of the leaves D E being housed in the stock, while the blade 0 extends at an angle thereto.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. A combined bevel and miter comprising a stock, a blade pivotally connected thereto, a second blade pivotally connected to the stock and having a longitudinal slot, and leaves pivotally connected together and to the first-named blade and stock, and having a lateral projection arranged to be pushed endwise into and withdrawn from the slot of the second-named blade.

2. A combined bevel and miter comprising a stock, a blade pivotally connected thereto, a second blade pivotally connected to the stock and having a longitudinal slot, resilient leaves pivotally connected to the first-named blade and the stock, respectively, and a pintle pivotally connecting the adjacent ends of rower the leaves and having an extended portion adapted, by reason of the resiliency of the leaves, to be sprung endwise into and out of the slot of the second-named blade.

3. A combined bevel and miter comprising a stock, a blade pivotally connected thereto, a second blade pivotally connected to the stock, and having a longitudinal slot, leaves pivotally connected together and to the firstnamed blade and stock, and having a lateral projection arranged to be pushed endwise into and withdrawn from the slot of the secondnamed blade, means for adjustably fixing the first-named blade and the leaves with respect to the stock, and means for adjustably fixing the second-named blade with respect to the stock.

4. A combined bevel and miter comprising a stock having a division-plate and side sections, and also having the pockets h 'i j and the notch k, blades B, C, the former of which is slotted, a transverse bolt pivotally connecting said blades and the stock, and having screw-threaded ends and nuts thereon, and leaves pivotally connected together and to the stock and blade 0, respectively, and having a lateral projection arranged to be pushed endwise into and withdrawn from the slot of blade B.

5. A combined bevel and miter comprising a stock having a division-plate and side sections, and also having the pockets h t' j and the notch It, blades B, O, the former of which is slotted, a transverse bolt pivotally connecting said blades and the stock, and having the collar f, and also having screw-threaded ends, and nuts thereon, and leaves pivotally connected together and to the stock and blade 0, respectively, and having the notches n in their inner edges, and also having a lateral projection arranged to be pushed end wise into and Withdrawn from the slot of blade B.

6. A combined bevel and miter comprising a stock, blades pivotally connected to the stock upon a common axis, and leaves pivotally connected together and one of them to one of the blades and the other to the stock, and adj ustably connected to the other blade; the'said leaves being of a greater length than the distances between the points at which they are connected to the stock and blade and the point Where the blades are connected to the stock, whereby an increased range of action is afforded.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
